Pate ents Number 2,028,560 or January 21, 193s; 2,093,696 of Septemberil; 1931;1368502 of-June 24 l930-or1,565-,- 218 f December 8-; 1925;- wherein thethread cutterusually in scissors or shears extendsthrough a slot in the side of theshuttle-soas to pass astride theoutgoing filling fonseveringthe same.

Now, in theuSual type of shuttle, there is a longitudinally extending-"groove extending all the W y alon theside iancl ebout e v of the height of the shuttle in which the outgoing thread from the bobbinv is disposed ina boxin operation. However, it often happens that, in the bOXing Qf the shuttle, it will rebound slightly and, also,the filling is pinched between the box frqnt and the side of the shuttle. It ofte n hapthat-there will-be slach-occurring-on that portion of; the filling which extends across the slot; in the-shuttle to allow the filling tofdrop downwardly to a pointwhere the shears'will not straddle the same and thus the filling will not be parted when the shears are closed.

It is an object of this invention to provide means on each side of this slot in the shuttle for retaining the thread in a straight position and causing it to bridge the slot in the shuttle in a straight line and in its proper position, said means comprising a member disposed adjacent each end of the slot and across which the filling is passed and said means having a fuzzy or fiber like texture so the filling will attach itself to the fibers extending from the members and thus prevent the filling from falling downwardly, by gravity. These members are preferably made of animal hide such as a sheeps hide with the wool left thereon and sheared to the proper length so as to project only slightly beyond the outer surface of the shuttle, said hide being suitably secured in suitable cavities disposed in the side of the shuttle and on each side of the slot through which the thread cutter passes.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure 1 is a top plan view of a shuttle with which my invention is associated;

Referring more specifically to'the drawings, the numeral l0 indicates a conventionalshuttle of the type used in an automatic filling transfer loom equipped with a forked spring member I I for holding the butt of a bobbinl2 whichhas; filling yarn l3 thereon. The-shuttle lliisalsoequipped with 'a conventional shuttlereye; i4; and the filling 1-3 is drawn from the. tip of: the bobbin through theshuttle eyevand passesiout intora grooveindl cated at. is and passes. across: and alongside the outer side of the shuttle, and baclo into theshed of the cloth beingwoven by theloomi The, conventional shuttle. has an elongated slot or open.- ing ll: in the sidethereof which is proyided: solth e thread cutteror shears, such, as are shown. in any one. of the abovernoted patents,=especially- Pate entsrNnmber:1,558,2l8;or 2 09.3,696; may enter.

' As. heretoforev stated, the side ofthe shuttle nearest the observer in Figure 2 is usually provided with a longitudinal extending groove on that portion of the shuttle which will be engaged by the box front for accommodation of the filling thread l3 on its way from the eye of the shuttle to the selvage' of the cloth being woven but, as before stated, sometimes the shuttle rebounds a bit and causes slackness in the filling so that, al-

ta en a o though it may be pinched against the side of the shuttle by the box front, that portion of the shuttle in which the slot I! is disposed is usually of slightly smaller cross sectional dimensions than the rest of the shuttle so as not to pinch the thread on both sides of the slot I! and as a result, when the shuttle rebounds slightly, the thread will sag down out of the path of the shears of the cutter and therefore will not be severed in a severing operation.

In order to overcome this difiiculty in my shuttle, I have been able to dispense with the usual longitudinal extending groove in the side thereof because it is not needed and, in lieu thereof, I have provided a pair of cavities 20 and 2| on each end of the slot l1 and each of these cavities has suitably secured therein such as by a suitable adhesive, a suitable member such as a piece of sheep skin 23 having the wool left thereon. This wool projects outwardly, as indicated at 24, slightly beyond the outer surfaces of the shuttle so that, as the filling thread I3 is passed across the slot 11 in a weaving operation, the same will adhere and cling to the wool or other fibrous, nappy material 24 on the members 23 and will therefore be prevented from falling downwardly and will remain in fairly taut condition bridging the slot H as shown in Figure 3.

It is thus seen that I have provided means for retaining the filling thread on the exterior of the shuttle in a straight line and approximately midway between the top and bottom walls of the slot I! so that the thread cutter will properly engage the same when a transfer operation is taking place.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. A shuttle having means for supporting a bobbin therein and having a shuttle eye through which the filling thread from the bobbin extends and having a slot in one of its side walls for the accommodation of thread cutting means, means for maintaining the outgoing filling in substantially taut condition across said slot comprising a pair of members, there being one member disposed at each end of the slot and having a napped or soft fibrous surface to which the filling will adhere and to thus maintain the filling in substantially straight condition across said slot.

2. In a shuttle for looms having means for holding a bobbin therein having filling thread thereon, and having a shuttle eye through which the filling thread extends, said shuttle having an elongated slot in one of its sides for the reception of thread cutting means, means 'for maintaining the filling thread in a substantially straight line and approximately midway of the top and bottom of said slot comprising means disposed adjacent one end of the slot and having a napped outer surface across which the 4 filling thread is drawn for maintaining the filling thread in a substantial medial position longitudinally of said slot.

3. An improvement in a shuttle for looms, said shuttle having a side wall and also having means for holding filling thread therein and also having a shuttle eye through which the filling extends, said improvement comprising a fuzzy textured member secured to the outer surface of said side wall adjacent said shuttle eye and across which the filling thread is adapted to be drawn whereby the filling thread will adhere to said member to maintain the elevation thereof.

4. In a loom shuttle having a slot in one of its side walls for the reception of thread cutting means, fibrous means disposed on each side of the slot and projecting slightly beyond the exterior surfaces of the shuttle and across which a filling thread is adapted to be drawn and the nappy texture of the members serving to cause adherance of the filling thread thereto to maintain the filling thread in elevated position.

5. An improvement in a shuttle of the type used on automatic filling replenishing looms in which a thread cutter is employed for severing a filling thread carried by said shuttle, said improvement comprising at least one member having a fuzzy texture secured to said shuttle at a point adjacent the point at which said thread cutter operates upon the filling thread and across which the filling is adapted to be drawn whereby the fuzzy texture of said member will serve to cause adherance of the filling thereto to maintain the filling in elevated position.
